2003 Jaguar X-Type Question: upstream O2 sensor bank 1 diagram

I need to replace both O2 sensors for upstream bank 1 but not too sure exactly which sensor, please supply picture diagram, thanks -
Answer 1
I have no picture or diagram. The upstream O2 sensors are before the catalytic converters and the downstream sensors are behind them. I believe that the upstream sensors are in the exhaust manifolds. You'll have to look for yourself. Bank one is the side of the engine that has #1 cylinder, FYI.
